Answer 3

<connection-url >jdbc:mysql://localhost/mydata </connection-url > 应该指定下端口号；@PersistenceContext(unitName="myspace") 你把unitName="myspace"先去掉看哈行不行，  
我没有用unitName参数，但我的ENTITY BEAN是行的， 
你也可以先看看是不是unitName这个参数？？这个unitName参数有没有错哦？？先去确认哈， 看是不是这个参数。

是mbean 的依赖关系出的问题 我也遇到了 Mbean在EJB3服务启动之前启动了。也正在寻找解决方法
